ANNUNClATOR-DROP.

SPECIFICATION forming part of Letters Patent No. 228,578, dated June 8, 1880.

Application filed March 6, 1880.

To all whom it may concern Be it known that I, JNo. M. WHEELER, of Toledo, county of Lucas, and State of Ohio, have invented certain new and useful Impro vements in Drops for Telephone-Signals; and I hereby declare the following to be a full, clear, and exact description thereof, reference being had to the accompanying drawings, making a part of this specification, in which-- Figure 1 is a perspective view of my invention, showing the drop up and in position. Fig. 2 shows the drop in the act of falling.

The object of my invention is to secure some reliable signal for a telephone-call, and some certain means of showing that the call has been exhausted and it is desired that-the line be placed in normal condition.

It consists of .the combination of devices hereinafter described and claimed.

In the drawings, A represents a magnet, with the usual frame-work, B, for holding the drop. Heretofore the drop has been pivoted at its lowest points, so as to fall down with a turn to expose the opposite or figure side of the drop. The result of this construction was to throw out the same side of the drop every time it fell, and when replaced there was nothing to indicate that the telephone had been (No model.)

at F, and when the drop is released from its catch by the magnet it falls, as shown in Fig. 2, upon the rest G, and exposes its numbered side, the blank side being down. In replacing the drop it may he turned on its pivots or journals so as to throw the numbered side to view, thus showing that the wire is then being used by that number. When the party finishes with the wire and makes a ring-out signal the drop again falls, but this time with the blank side exposed, showing that the party using the wire had finished and desired the wire to be placed in its normal condition. This becomes a matter of great importance where hundreds of different parties are constantly using the telephone and it is necessary to remember and note when each one has finished and avoid interruption and confusion.

Having thus explained my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In combination with a magnet, A, and frame B, the drop 1), journaled at or near its center on the pivoted arms E, substantially as and for the purpose set forth.

2. The drop D, made reversible, substantially as shown, whereby two different signals may be given by the same drop, as herein de scribed.
